Lu Guangzu (Chinese: 陆光祖; pinyin: Lù Guāngzǔ; Wade–Giles: Lu Guangzu; born on 19 October 1996) is a Chinese badminton player. In 2018, Lu made into his first final at the Lingshui China Masters. Since then, he both won Australian Open and Canada Open's titles.
Lu reached the final of the Australian Open, his first final in four years, defeating world No.2 Lee Zii Jia en route. Although he lost to compatriot Shi Yuqi in three games, he qualified for the World Tour Finals for the first time in his career. In his group, he defeated Prannoy H. S. in a tight three-game match, but failed to qualify for the semi-finals as he lost to world No.1 Viktor Axelsen and Kodai Naraoka, both in straight games.
